GSoC : This week in SymPy #1

Hi there! The First week of the coding period has came to an end, this week has been very hectic for me due to my practicals and Minor project submission at college, though I mananged to reach the goal for this week.

This week, I worked on Linear system solver linsolve in the solveset Module, as I mentioned in my last post, about my goals for Week 1.
